Title: Automatic sidetone selector
Inventor: FORRESTER CHRISTOPHER M
IPC: H04M1/58
Filed: 1992-12-31
Granted: 1996-04-09
Abstract: Sidetone in a four-wire telephone station set that is coupled to a two-wire telephone line through a four-to-two wire hybrid circuit is automatically set by incrementally adjusting a balancing impedance connected to the circuit until an optimum impedance match between the telephone set and line is achieved.  Under software control, during idle intervals between dialed digits when a call is initiated, a microcontroller mutes the telephone transmitter and receiver on the telephone side of the circuit and substitutes for these components a tone signal generator to produce a sidetone signal that is applied to a full-wave rectifier and therefrom to a peak voltage detector to generate a sidetone envelope.   Individual ones of several impedance balancing networks are then sequentially connected to the telephone side of the circuit and the sidetone envelope for each balancing impedance is digitally encoded and stored.  A mutual comparison of the stored data indicates a minimum sidetone value which corresponds to an optimum impedance match that is retained unless a subsequent telephone call results in a change of balancing impedance.

Title: Carrier phase estimation system using filter
Inventor: KATAOKA NOBUHISA
IPC: H04L27/233
Filed: 1994-01-10
Granted: 1999-11-16
Abstract: A carrier phase estimation apparatus including a base band converter and a phase estimator. A received IF signal is converted to an in-phase component In and an quadrature component Qn of a digital base band signal in the base band converter. In the phase estimator, a non-linear circuit executes a non-linear operation of the components In and Qn to output non-linearly converted in-phase component In' and quadrature component Qn' of the digital base band signal and the components In' and Qn' are input to a pair of filters.      In each filter, the components In' or Qn' are stored into shift registers at a predetermined timing and the signals stored in the shift registers are multiplied by respective weighting factors C k in respective multipliers. The multiplied values are summed by an adder and the obtained sum is divided by a stage number N of the shift register in a divider to obtain filtering signals Xn and Yn. That is, the weighted averaging of the components In' and Qn' is taken in the filters and then the filtering signals are transformed in a coordinate transformer to calculate an estimated carrier phase ~n. By taking the weighted average, the carrier phase fluctuating due to fading can be more precisely estimated.

Title: Connection-oriented congestion controller for common channel signaling network
Inventor: TOPPER JEFFREY
IPC: H04L12/24
Filed: 1994-01-11
Granted: 1998-08-11
Abstract: A connection-oriented congestion controller for a common channel signaling network comprises a memory for storing data representative of established connections, and a data transceiver connected between user terminals and remote signaling nodes for receiving and sending data messages on the established connections.  The data transceiver is responsive to a blocking status indication for imposing flow control on the data messages and marking the established connections as blocked in the memory, and is responsive to an unblocking status indication for removing the flow control and marking the established connections as unblocked in the memory.  A resource monitor compares a resource availability value with a number of thresholds, and produces the blocking status indication when it becomes lower than a start-of-blocking threshold until it becomes higher than an end-of-blocking threshold, and initiates the unblocking status indication when the resource availability value becomes greater than a start-of-unblocking threshold when at least one established connection is being blocked and continues the unblocking status indication until the availability value becomes less than an end-of-unblocking threshold or until there is no established connection which is blocked.  When the established connections are marked unblocked in the memory, the resource monitor compares the resource availability value with a new connection threshold to determine whether a new connection request is to be allowed or refused.

Granted: 1999-02-16
Abstract: The invention relates to continuous positive airway pressure (CPAP) respiratory therapy apparatus for treatment of apnea, hypopnea and other sleep disorders, and particularly to a standby control for automatically operating an air blower in CPAP apparatus. A blower is connected through a hose and a mask, such as a nasal mask or a nasal cannula, to the patient's respiratory airway. Initially, the blower is in a standby mode in which it is either turned off or, preferably, operated at a low speed. When a patient starts breathing through the mask, the blower is automatically switched to an operating mode. In the operating mode, the blower may be controlled to initially supply a low air pressure to the mask which either is increased after a sufficient time delayto allow the patient to fall asleep or is increased in response to the detection of a respiratory event such as apnea or hypopnea. If patient breathing through the mask ceases because the mask has been removed or otherwise is no longer sufficiently sealed to the patient's airway, the blower is automatically returned to the low pressure standby mode. If the patient does not begin breathing through the mask within a predetermined time, the blower is stopped. An optional recorder measures the total time that the patient is breathing through the mask or the total time that the blower is in the operating mode to provide the prescribing physician or technician with patient compliance information.
